Specification of Letters Patent.

- Patented Nov. 23, 1909.

Application filed July 13, 1908. Serial No. 443,210.

To all whom it may concern:

Be it known that I, HARRY L. SNEDIKER, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Syrup- Pumps forSoda-Fountains; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to a syrup pump for soda fountains, and has for itsobject to provide a device of that class whereby a clesired and definitequantity of syrup may be pumped from a fountain tank at each opera tionof a pump plunger.

A further object of my invention is to provide a pump mechanism, thecomponent parts of which may be separated to facilitate cleansing.

A further object isto provide an improved plunger cup, and means wherebythe stroke of the plunger may be varied to vary the quantity of syrupdischarged at each manipulation of the pump. I

A further object is to provide a nozzle by which the usual dripping ofsyrup after each operation of the pump may be obviated.

A further object is to provide other improved details of structure whichwill presently be fully described and pointed out in the claims,reference being had to the accompanying drawings, in which Figure I is alongitudinal vertical section of an ordinary syrup jar having adepressed pump chamber and containing'a pump constructed according to myinvention. Fig. II is a top planviewof the same. Fig. III is ahorizontal section taken on line III-III, Fig. I. Fig. IV is ahorizontal section taken on the line IVIV, Fig. I,- showing the pump capanchoring parts. Fig. V is a plan view of the plunger; the plunger rodbeingshownin section.

Referring more in detail to the parts:1 designates a syrup jar,comprising a bottom pump chamber 2 andcover 3, the latter hav-v ing anopening 4: located over the chamber 2 through which the pump is insertedinto the jar.

The pump structure comprises a plunger cup 5, thatis adapted to fitsnugly within the chamber 2 in the syrup jar, and has the recesses 5' inits upper side edges through which syrup is admitted to the cup, saidcup being preferably provided with a bottom cap 6 that is threaded ontothe cup body to form a closed plunger chamber that will effectuallyconfine. the syrup during the pumping process but which may be easilyremoved to facilitate cleansing of the cup and pump parts. Cup 5 is openat the top and provided at the back and front, with the inwardlyprojecting flanges 78, the former of which is only of sufficientthickness to support a standard 9, while the latter is extended by acylinder 'memberlO to within a short distance of the bottom of the cup,the flange 8 and cylinder member being preferably integral and having acontinuous channel .11 that communicates with the cup chamber through aconduit 12 beneath the member 10, andthrough which the syrup from thecup is forced upon the descent of the plunger, as will presently be setforth. Fitting within a seat in the flange 8 is a tube 13 which extendsupwardly to the height of the standard 9 and has a channel registeringwith the flange 8 and cylinder channel 11.

lt designates the pump cap which is supported 011 the cover 3 by theflange 15 and has a reduced portion 16 of its body projected into thecover opening and has the sockets 17-18, within which the respectiveupper ends of the standard 9 and tube 18 project, such body portionhaving a lip 19 which projects forwardly there-from and is adapted toseat in a recess 20 in the cover 8, in order to anchor the pump capagainst lateral movement.

21 designates a nozzle which is preferably formed integral with the capbody and extends outwardly therewith at an upward incline and has achannel extending therethrough, and registering with the channel of tube13, the tip 22 of such nozzle having an interior flange 23 projectinginto the nozzle channel, to obviate dripping'of the nozzle after anoperation of the pump.

The interior of cap 14 is chambered and provided with a depending barrel2 L, that is preferably of skeleton formation and has its upper endthreaded into a suitable flange 25 of said cap.

26 designates a plunger rod which projects through perforations in thepump cap and barrel, and extends downwardly into the cup 5, the lowerend of such rod having an adjustable threaded connection with theplunger 27, which fits within the cup and is adapted for verticalmovement therein. Plunger 27 is slotted at its forward edge to embracethe cylinder member 10 by which it is guided in its vertical travelbeneath the flanges 7-8 and the bottom of the cup, and is adapted forengagement with the under faces of said flanges to prevent itsdisplacement on the up stroke of the rod.

28 designates a collar on rod 26, and 29 a coil spring which surroundssaid rod with its respective ends in engagement with the bottom ofbarrel 24E and'the under side of collar 28, the latter being adapted tonormally tension said rod upwardly and retain the plunger 27 in itsengagement with the under side of flanges 7 and 8. On the portion of rod26 which projects above the pump cap is a knob 30 within which a button31, bearing suitable wording, may be located, said knob having athreaded rim flange 32 for retaining the button in its seat.

Inasmuch as syrup tanks, or jars, similar to that shown in the drawingsare commonly used, no special equipment is necessary in applying thepump to different styles of fountains; the only change necessary to bemade for the mstallation of the present pump being the cutting of therecess 20 in the cover 3 for the lip 19.

Presuming the ar to be provided with the cup chamber 2 and the coverwith opening 4 and recess 20, the pump, which is assembled as described,is inserted through the cover opening until the cup 5 seats in chamber 2and the cap l seatsin opening t, when the lip 19 will fit within therecess 20 and prevent lateral movement of the parts.

When the pump is located as described, syrup will flow through theintake recesses in the upper side edges of the cup and fill the latter,so that a measure of syrup is constantly in condition for discharge.

hen a measure of syrup is desired, the plunger rod 26 is depressedagainst the tension of the spring 29, by pressing on the knob 30,thereby forcing the plunger 27 downwardly in the cup 5. During the firstpart of its descent, the plunger 27 forces the syrup out through therecess 5 into the jar, but as the plunger passes such recess its closefit in the cup moves the syrup up through the cylinder chamber 10, andtube 13 to the nozzle 21 from which it is delivered to a receptacle thatmay be held therebeneath. After the syrup has been discharged, thepressure on the knob is released and the spring 29 returns the rod andplunger to their original position, a suction being created in the tubeand nozzle as the plunger moves upwardly. in the cup which tends to orthe plunger and that when the rod is turned it will move downwardly orupwardly, against or with the tension of spring 29 to lengthen orshorten the portion below the plunger. In this manner the measure ofdischarge may be regulated because of the variance in the distance theplunger may travel before the end of the rod strikes the bottom of thecup; an extended travel of the rod increasing the measure of syrup and alimited travel diminishing the measure.

By constructing the pump in a number of pieces that may be separatedfrom each other, the pump may be knocked down to render the partsconvenient for cleaning and thereby afford a sanitary structure.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patentis 1. A syrup pump comprising aplunger cup formed with recessed edges, with in-I wardly projecting backand front flanges and with a cylindrical member beneath the front flangeleaving a conduit therebeneath, and having a removable cap for closingthe bottom of the plunger cup, means for conducting the fluid from thecylindrical member, and a plunger formed with a slot at its front edgereceiving the cylinder chamber and havin a rod and adapted to be removedthrough the bottom of the plunger cup.
